any-sized PNG can be loaded and then scaled to the available space.

having to know about TIA, Properties, etc. Basically, it now saves
a snapshot of either the FrameBuffer or an FBSurface, and adds
text comments passed into it. The contents of the surface and comments
are no longer calculated (or known) by the PNG code.
This is in preparation for saving FBSurface from anywhere, which will
help in the debugger for taking snapshots.

which I though a just a one or two-liner equivalent to glReadPixels.
Turns out that SDL2 doesn't return 24-bit RGB data (only 16 or 32-bit),
so the PNGLibrary had to massage the data. In the process, converted
the PNG saving functions to actually use PNG library functions, which
greatly simplified converting packing from 32 -> 24-bit. Historically,
the PNG save functions were written before libpng was a requirement,
so they were hand-rolled. Once libpng was integrated into the codebase,
it didn't make much sense to not use it anymore.
So an expected two-line code fix became this commit ...

reading these commit logs.

Moved TODO and Credits info directly to the webpage, where it will hopefully
be easier to maintain.
Fixed 'crackling' sound when loading a new ROM, introduced with the 3.5
sound restructuring. It looks like stale data was being loaded by the
sound processing callback. As well, moved the computation of certain
division variables from the sound callback to the framerate re-calculator
(where it's recomputed 1/5 of the time or less).
Updated AboutDialog with info about Stella DonationWare status, and active
members of Stella development.
Updated OSX in-app HTML documentation about Stella DonationWare status.
Bumped version # to 3.5.1_svn, and the process starts again.

of the C++ standard.
Fixed bug when using snprintf; we must use BSPF_snprintf, since the function
has different names in different OS's.
Optimized loading of PNG images in the RomInfoWidget so that memory allocations
aren't continuously being done. Basically, memory is allocated once and then
only re-allocated if a new image is larger than all previous ones. This can
increase memory use slightly, as the image data stays around between image loads,
and it remembers the largest image loaded. But if you images are all mostly the
same size, it should hurt memory usage too much. And it really helps on certain
systems where repeated (re)-allocations can cause problems.

console (which doesn't exist on every platform). Also use proper C++
stringstreams instead of C-style arrays (which are evil). If an exception
is thrown, start the debugger with a fatal error message. Currently, this
message is simply printed in the debugger info window. Still TODO is add
a dialog to show the entire input from within the UI, as well as a way
to exit the ROM when a fatal error occurs.
Cleaned up the API a little, adding explicit declarations for when a method
can throw an exception. Also merged some empty classes directly into their
header files.
Added functionality to the System class for querying whether it has
been reset while in 'autodetect' mode. Autodect mode is defined as
when Stella starts and temporarily runs to autoconfigure itself.
Some classes (such as Thumb ARM emulation) need to know this, and
suppress debugging output/throwing exceptions when not running in
normal emulation mode.
I hope to have a new release done by the end of this week, or the end
of the month at the latest.

the various header files. Basically, I'm following advice from
Effective C++, and including only what's absolutely necessary. For
definitions that don't need to be included, the designation 'class xxx'
is used instead. This could potentially lead to faster compile times.

Updated the non-Intel XCode project to include libpng support.

similar to the recent Zlib addition. This is required for the
RomListWidget, which currently doesn't parse valid PNG files
that are generated outside Stella (in particular, those that
have been optimized and use row filtering).
